Exception when connection is closed


RobinCirex

Recommended Posts

Hey I'm making a mod that has a connection between the server and the client using a SimpleNetworkWrapper

When a player disconnects, the server throws this exception

The german part basically means that the Hostcomputer closed the connection through the software. 

It doesn't really have any side effects, it still bothers me and wanted to ask how to fix this error

...and your mod's code?

Apparently I'm a complete and utter jerk and come to this forum just like to make fun of people, be confrontational, and make your personal life miserable.  If you think this is the case, JUST REPORT ME.  Otherwise you're just going to get reported when you reply to my posts and point it out, because odds are, I was trying to be nice.

 

Exception: If you do not understand Java, I WILL NOT HELP YOU and your thread will get locked.

 

DO NOT PM ME WITH PROBLEMS. No help will be given.

well, there isn't much to show. 

This is the networkwrapper being initiated

	@EventHandler
	public void preInit(FMLPreInitializationEvent event) {
		networkWrapper = NetworkRegistry.INSTANCE.newSimpleChannel("settlementchannel");
		networkWrapper.registerMessage(Message.ClientHandler.class, Message.class, 0, Side.CLIENT);
		networkWrapper.registerMessage(TaxMessage.ClientHandler.class, TaxMessage.class, 1, Side.CLIENT);
		networkWrapper.registerMessage(ArmyMessage.ClientHandler.class, ArmyMessage.class, 2, Side.CLIENT);
		networkWrapper.registerMessage(UserMessage.ClientHandler.class, UserMessage.class, 3, Side.CLIENT);

Nothing happens in the PlayerLoggedOutEvent except this

	@SubscribeEvent
	public void onLeave(PlayerLoggedOutEvent event) {
		User user = SettlementMod.getInstance().getUserManager().getUser(event.player);
		if (user != null) {
			user.player = null;
		}
	}

which is just looping through an arraylist and has nothing to do with networking

there is also no "constant connection" the server only sends information to the client on a specific event

Not sure if this is it but doesn't this method have 4 parameters? It's in the docs and it seems pretty important. It seems like you are working for an unsupported version, please update to a modern version on Minecraft to receive support.

To break it down, FMLPreInitializationEvent no longer exists, @EventHandler no longer exists and your message registration code is completely different than it is in supported versions.

It's sad how much time mods spend saying "x is no longer supported on this forum. Please update to a modern version of Minecraft to receive support".

Yes, this mod is for 1.12 as it's an addon for pixelmon and that only exists for 1.12

1.12 is no longer supported here. Your options are:

  • Update
  • Go somewhere else for help

    • Hello. I'm using IntelliJ IDEA and making a mod for Forge 1.20.1 and I'm trying to make a GUI. I found that the Minecraft-related codes are all obfuscated and when setting up the workspace, Gradle did not execute Deobfuscation tasks like createMcpToSrg. Is this normal or a bug? Can anyone help me with this?
    • Hello! I'm trying to get a list of all entries registered in the infusion upgrade registry. Code can be found in github: https://github.com/ChamoisEST/MiningMadness/tree/1.20.1 Registry in common/registries/MMRegistries.java Event that calls the registry is in MiningMadness.java List of registered entries should be called in common/capabilities/infusion/InfusionCapabilityImplementation.java:getActiveInfusions() in the for loop. Is there any way to accomplish that? Thanks in advance!  
    • So, I am trying to create and add tags to my custom damage type, but looks like I made something wrong, since it crashing with error that "cannot register" damage type. Im trying to register it, and in datagen add tags, but it everytime crashing due to not register "grimtales:entropy". Full code there - https://github.com/undertakerJ/Grim-Tales-Forge ModDamageTypes class public class ModDamageTypes { public static final DeferredRegister<DamageType> DAMAGE_TYPES = DeferredRegister.create(Registries.DAMAGE_TYPE, GrimTales.MOD_ID); public static final ResourceKey<DamageType> ENTROPY_KEY = ResourceKey.create(Registries.DAMAGE_TYPE, new ResourceLocation(GrimTales.MOD_ID, "entropy")); public static final RegistryObject<DamageType> ENTROPY = DAMAGE_TYPES.register( "entropy", () -> new DamageType("entropy_effect", DamageScaling.ALWAYS, 1f, DamageEffects.HURT)); // // public static final DamageSource ENTROPY_SOURCE = new DamageSource(Holder.direct(ENTROPY.get())); public static void register(IEventBus eventBus) { DAMAGE_TYPES.register(eventBus); } } Datagen for damageTags public class ModDamageTagsProvider extends DamageTypeTagsProvider { public ModDamageTagsProvider( PackOutput p_270719_, CompletableFuture<HolderLookup.Provider> p_270256_, @Nullable ExistingFileHelper existingFileHelper) { super(p_270719_, p_270256_, GrimTales.MOD_ID, existingFileHelper); } @Override protected void addTags(HolderLookup.Provider pProvider) { this.tag(DamageTypeTags.BYPASSES_INVULNERABILITY).add(ModDamageTypes.ENTROPY_KEY); } } Datagen class it self   @Mod.EventBusSubscriber(modid = GrimTales.MOD_ID, bus = Mod.EventBusSubscriber.Bus.MOD) public class DataGenerators { @SubscribeEvent public static void gatherData(GatherDataEvent event){ DataGenerator generator = event.getGenerator(); PackOutput packOutput = generator.getPackOutput(); ExistingFileHelper helper = event.getExistingFileHelper(); CompletableFuture<HolderLookup.Provider> lookupProvider = event.getLookupProvider(); generator.addProvider(event.includeServer(), new ModDamageTagsProvider(packOutput, lookupProvider, helper)); } } And register class in main class public GrimTales() { IEventBus modEventBus = FMLJavaModLoadingContext.get().getModEventBus(); ModDamageTypes.register(modEventBus); modEventBus.addListener(this::commonSetup); MinecraftForge.EVENT_BUS.register(this); modEventBus.addListener(this::addCreative); }  
    • Looking for a semi-vanilla Minecraft server? Maybe one with keep inventory and land claims? I have one for you! Let me introduce you to Safe Survival! Come on and join us at mc.safesurvival.net. It is bedrock supported too!
    • Hi. I'm trying to play RLCraft with Optifine but my game keeps crashing on startup with Exit Code 1. The modpack was working fine yesterday, not sure what changed to make it not wanna work anymore. I was hoping someone here could help me figure out what's going wrong. If I remove Optifine, nothing changes, I still get the same errors. Thanks in advance. Crash Report (I only included the errors+fatal, I’m not sure if more is needed, please let me know): https://pastebin.ai/66ivknz0f4
